In addition, the 'ChannelBelt' object also has a 'cl_times' and a 'cutoff_times' attribute that specify the age of the channels and the cutoffs. These are implemented as classes a 'Channel' and a 'Cutoff' are defined by their width, depth, and x,y,z centerline coordinates, and a 'ChannelBelt' is a collection of channels and cutoffs. The sketch above shows the three 'meanderpy' components: channel, cutoff, channel belt. In the 'meanderpy' module we use a simple linear relationship between the nominal migration rate and curvature, as recent work using time-lapse satellite imagery suggests that high curvatures result in high migration rates ( Sylvester et al., 2019). Curvature is transformed into a 'nominal migration rate' through multiplication with a migration rate (or erodibility) constant in the Howard & Knutson (1984) paper this is a nonlinear relationship based on field observations that suggested a complex link between curvature and migration rate. This is a kinematic model that is based on computing migration rate as the weighted sum of upstream curvatures flow velocity does not enter the equation. Says you, not us we believe the opposite.'meanderpy' is a Python module that implements a simple numerical model of meandering, the one described by Howard & Knutson in their 1984 paper "Sufficient Conditions for River Meandering: A Simulation Approach". I'm glad that John and Ed are running Disney Animation and not you, cause from what you've been saying, your bias for loving hand drawn and hating CG would have crippled Disney Animation. This is the kind of mentality that Michael Eisner had when he destroyed Disney! Ed Catmull clearly stated that the mentality of "Disney should be Hand Drawn and Pixar should be CG" is completely unacceptale. That is a very selfish, greedy, stagnant and thoughtless way of directing a studio. If they want a CGI film, they should stick with Pixar making them. And for the record, when exactly was Bolt released? I'm pretty sure it wasn't around the time an anticipated hit occurred.Īnd for the record, Walt Disney Studios was the pioneer of traditional animation, so it actually should stick to traditional animation. They are acting as though it was literally just the medium that caused them to underperform rather than the fact that they were unlucky enough to be released at the same time as films that struck gold or were anticipated (Avatar for the former, and Harry Potter and the Deathly Hallows Part 2 for the latter). Princess and the Frog and Winnie the Pooh was also critically acclaimed as well, yet you don't see them continuing the traditional animation route with them. I just so happens that Disney Animation isn't one of them. There's plenty of studios still doing hand drawn animation. All their CG movies since Tangled have been critically acclaimed! Besides, Feast also uses the Meander animation style. I will acknowledge that The Matrix was probably doomed even if they didn't resort to CGI because the Wachowskis were dead set on pushing nihilistic anarchy and Nietzschean philosophy, but not the other examples.īut Disney Animation is not suffering from that. Yes, profits are essential, but what good are profits, when most people don't even like the movie and they spread how the movie is bad and cause a loss of revenue? They all have that similarity at least. So far as your other claim, actually, all movie companies need to be driven not just by profit, but also good reviews to ensure they actually have done a good movie. Maybe because the Meander style has only been used once with Paperman, and hasn't been seen since? Why bother looking forward to it when they haven't even been using it? ![]() ![]() Why isn't anybody looking forward to the Meander animation style?
